绘制脚本中包含的数据会导致循环失败 [英] Plotting data included in script fails in loop

问题描述

我想绘制脚本文件中包含的数据点.这应该做多次(绘制到不同的文件).因此，我正在使用do-for-loop.

I would like to plot data points included inside a script file. This should be done multiple times (plotting to different files). Therefore, I am using a do-for-loop.

此循环让Gnuplot在执行时冻结.您能提示我原因吗?

This loop let's Gnuplot freeze on excution. Could you please hint me to the cause?

这是我的MWE:

reset
set autoscale

do for [index=1:1] {
plot "-" with lines ls 2 notitle
0.500 5
1.000 6
1.500 7
e
}

推荐答案

是的，似乎不支持将 do for 与内联数据结合使用.这也不是很方便，因为每次迭代都需要一个单独的数据块，例如

Yes, seems like the combination of do for with inline data isn't supported. It also wouldn't be very convenient, since this would require a separate data block for every iteration like in

set style data linespoints
plot '-' using 1:2, '-' using 1:3
1 2 3
4 5 6
e
1 2 3
4 5 6
e

在版本5.0中引入了内联数据块，这些数据块允许重复使用内联数据:

With version 5.0 inline data blocks were introduced which allow reusing inline data:

$data <<EOD
1 2 3
4 5 6
EOD
do for [i=2:3] {
    plot $data using 1:i w l
    pause -1
}
